A horizontal force is used to pull a 5.0-kilogram cart at a constant speed of 5.0 meters per second across the floor. The force of friction between the cart and the floor is 10. newtons v = 5.0 m/s Horizontal force 5.0 kg Floor 127. What is the magnitude of the horizontal force along the handle of the cart? 128. Calculate the weight of the cart. 129. Compare the weight of the cart to the normal force. 130. Calculate the coefficient of kinetic friction between the cart and the floor
